Abstract
A hoist ring assembly and related methods of lifting a load wherein the hoist ring assembly includes a bolt for securing the hoist ring assembly to the load and the bolt includes a tensile stress indicator for showing the tensile stress on the bolt when the bolt is tightened onto the load. The hoist ring assembly can further include a radio-frequency identification tag used for communicating information relating to the hoist ring assembly. The methods include using the tensile stress indicator to achieve and maintain a predetermined preload of the bolt, and using the radio-frequency identification tag to obtain historical recorded information relating to the hoist ring assembly.
